IMPRovEMENT IN sHovEL-eLows.

The Schedule referred to in these Letters Patent andmaking part 'of thename.

.'o all 'whom it may concern:

' Figure l is a side elevation of a shovel-plow, hav.

ing I ny improved axle-socket attached thereto.

Figure 2 is a'bottom view oi' my improved axlesockct, showing also howthe plow-beams are attached thereto, together with the method of bracingthe same.

Figure 3 is a sectional elevation of the socket, showing the end of thedraw-bar passing through it, and the brace upon its under side thereof,and connected with thc plow-beam.

`Figure d is a vertical section of the socket on line a: x of fig. 3,showing the method oi' attaching the end of the beam thereto. j

Figures 5, (i, and 7 are perspective views, showing the construction ofthe device for attaching the handles tothe beams.

Corresponding letters refer to corresponding parts in the severalfigures.

This invention relates to shovel-pious; and

It consists-w First, in the construction lof a metal socket for thcreception of the axle, and

Secondly, in the combination` and arrangement of the parts connectedtherewith, as will be more fully explained hereinafter.

A A refer to the beams of the plow, `which may he of metal, and bent, asshown in iig. 1, and he supplied with shovels 'of any approved pattern,their front ends being secured to the socket C by rivets and bolts.

B refers to the handles, which are attached to a socket, F, bymeans ofwhich they are held in position.

C refers to a socket, to which the front ends of the' beams areattached, and to which the draw-bar is also attached by means of a bolt,or it may be by 'an extension of one of the beams of the plow, as shownin ig.'2.

The above recited parts form no part of the invention hereinclaimcd,.and, consequently, need not be more particularly describedhere.

D refersy to a socket, which is to have an aperture formed in it in alongitudinal direction, to receive a portion of the axle of the machine.

Upon one side of the socket there are to be formed one or moreprojections, as clearly shown in iigs. 1, 2, and 3.

These projections are provided with apertures,`

which extend through them vertically, their oiice being to receive thebent forward end of the plowbeam or of the draw-bar, as maybe preferred.

\Vhen the bent end of the plow-beam is used as a means of connecting theplow or plows to the socket D, it is to be so formed asthata portionthereof shall pass through the vertical aperture in said socket, suchbent and flat portion being provided with two shims, made dat upon theirinner surfaces, but in the form of a segment of a circle upon, theirouter surfaces, and of such dimensions that, when they and the bentportion of' the beam are inserted therein, they will ll the vertical'aperture in the socket D, and thus form a fnlcrum, upon which the beammay turn to any desired extent.

The above-described arrangement of parts is clearly shown at tig. 4,where D1 refers to the projections upon socket D, and Dz andD to theshims which fill the spaces between the sides of the beams A and thesocket.'

E refers to a brace, which extends from socket G to and connects withthe end of the beam or drawbar upon the under side of the projection Dlol'` socket D.

The rear end of this brace isfirmly bolted to F refers to a device whichis shown in figs. 1, 5,

6, and 7. y

It is s o constructed as to grasp the beam, flanges being provided uponits inner surface for that purpose, they being of a form toiit the edgesof the beam at the point where it is desirable to attach them, whileupon its outer surface anges are to project, placed at such an angle asto give the 'handles a proper position with reference'to the beam.

The flanges upon the outer surfaces of this de#v vice form, withthe bodythereof, a recess, into which the handle is placed, and a bolt is passedthrough it and the beam of the plow, which, when tlianut screwed downthereon, unit-es all. the parts firmly together, and forms a completesupport for the handles ofthe plow.

` Having thus described my invention,

That I claim, and desire to secure by Let-ters Pat'- v -pose set forth.

y2. The combination' ot' the sokei: D, shims 1)2v this specification inthe vpresence of two subscribing and D, and beam or draw-bm: A,substantially l:is witnesse :md for'tiie purpose set forth. 4LUPPELUPPEN.

3. The combination of the socket C or beam A,

brace F, and socket; D, substantial-ly as and for the Witnesses: R

purpose set forth. CHRIST HEEFT,

In testimony whereof, I have signed my name to' LEMUEL ALLEN.
